On my SC-05, the MCACC main measure does one position. The 3 position measurement comes from the standing wave correction. I had to go to the advanced measurements specifically for the standing wave portion and tell it to calibrate 3 positions. Otherwise it will just default to one. Not sure if the new incarnations of MCACC are the same.

I'm loving my SC-67 right now. Only a little more control over the bass would make me happier. But I'm not complaining. I like a lot of bass, as long as the other frequencies are there too. But it's something I can play around with later, when I have the time for it.

lol no not back of a van. It will be slightly used. A friend of mine bought it and he's not a big fan of it. He's pretty loaded and he owes me a good deal. I gave him a bunch of equipment back in the day.

I don't know what about it he doesn't like, but he said he finds it "complicated". I like complicated
